A hard head and a little backbone...

This hefty Titan Stainless Steel Skull got a Backbone Bar (TIAT design) added to it, using black and olive drab paracord, with a large Flat Gate Clip for attachment to a key ring or belt loop.  A couple of the end strands go around the clip and are tied in a double wall knot around all four strands, then trim and tuck the ends to finish.

The skull is large enough to use as a paperweight on it's own, although I prefer it with some knot work for lanyards/fobs, and I even tried one out to top a walking staff/cane.  When I get around to it, I'll add some glow-in-the-dark powder and epoxy to the eye sockets.

With a bit of epoxy in the divot on the underside of the skull and then placed over a screw that's still partially exposed above a cane/staff, it looks to work ok.  Just for decorative use though, as I think if it was used to clobber someone, it might end up getting launched instead.

Someone else may know of a more secure way to mount the skulls on a walking staff/stick/cane, maybe carving the top of the staff to fit the underside of the skull along with a screw/bolt and epoxy...

I've tried a couple of knot work attachments with the skull on the staff, with paracord going though the skull and then down through the staff lanyard hole in a loop, then weaving or headhunter knots around the staff, but haven't found one I really like yet...

I used large and medium clips on a wall knot paracord lanyard(navy blue), with a few spaced out Gaucho knots tied with orange Tether Cord.  This one's for clipping to a key ring, pocket knife, flashlight, etc. with the other end attached to a belt loop...
